The raid was launched yesterday after the attack which left 11 Egyptian policemen dead in Sinai's Sheikh Zuwayed region after an improvised explosive device exploded, the source said.
The source added that the army has also arrested 11 suspects and destroyed 16 vehicles, 22 motorcycles and 35 houses and shelters belonging to terrorists.
The militant attacks targeting police and military increased after the ouster of Islamist ex-president Mohamed Morsi last year. Many policemen and soldiers have been killed in the attacks.
The guards were killed during an exchange of fire with the unknown gunmen which led to an explosion at the checkpoint's ammunition storage.
